•

Remove drive insert bearing from inside of dropout. Bearing is a
slip fit so only light pressure from screw driver is required to
remove.

•

Tap down on pinion gear with plastic face hammer. After pinion is

removed, slide the bottom bearing out of dropout bore. If bearing
stays on pinion shaft, remove by hand or with split bearing puller.

Note: lower pinion bearing is angular contact so if pressure is

applied in the wrong direction it may come apart. If bearing comes
apart, it must be replaced.

•

Remove top driveshaft seal from dropout using small flat blade
screwdriver. Be careful not to scratch inner bore.

•

Remove top pinion bearings from upper bore by tapping them
lightly tapping from inside the dropout with non-marring punch.

•

Pry axle o-ring from dropout using small pick.
